Influence of biochar on the partitioning of iron and arsenic from paddy soil contaminated by acid mine drainage

Scientific Reports, Год журнала: 2025, Номер 15(1)

Опубликована: Фев. 10, 2025

Paddy fields contaminated by arsenic-containing acid mine drainage (AMD) may also have rich iron in soil. Whether this can be loaded onto biochar to passivate the dissolved arsenic is worth further exploration. Soil was mixed with prepared at 400, 550, and 700 °C incubated under alternating anaerobic aerobic conditions. Soil, soil solution samples were analysed using ICP-MS, FTIR, SEM, XPS, etc. The results showed that lower pyrolysis temperatures contained a higher number of functional groups. Under combined action microorganisms, primarily from Firmicutes phylum, promoted dissolution oxides soil, residual undergoing transformation. rapidly its surface, likely form Fe3O4 FeOOH, adsorbed as As(III). Although detached over time, they more stable on 400 compared those temperatures. Meanwhile, content increased, raising As/Fe molar ratio above This study lays foundation for exploring long-term use AMD-contaminated paddy fields.
